Important Information
Reporting Defects
The units were inspected before shipment and found to be free of
mechanical and electrical defects.
Examine the units for any damage which may have been caused in
transit. If damage is discovered, file a claim with the freight carrier
immediately. Notify Foxcom as soon as possible.
Note Keep all packing material until you have completed the
inspection.
Precautions
Personal Safety
OPTICAL RADIATION
Applying power to the transmitter unit will create a laser energy
source operating in Class I as defined by IEC 825-1. Use either an
infrared viewer, optical power meter or fluorescent screen for optical
output verification.
AC P
OWER HAZARD
The rackmount power supply line is EMI filtered. The chassis is
connected to earth ground in compliance with safety requirements.
Always use the 3-prong AC plug with earth ground to avoid
possibility of electrical shock hazard to personnel.
Equipment Safety
To avoid damaging your product, please observe the following:
1. The output of the receiver is AC coupled and can withstand the
bias from a satellite receiver.
Do not exceed 25V DC bias.
2. The input of the transmitter has an optional built-in bias for
inserting DC power up the coax to the LNB. Make certain that
any equipment or test equipment connected to the transmitter
input can withstand this bias.
3. Do not allow any dirt or foreign material to get into the optical
connector bulkheads. This may cause damage to the polished
optical connector end faces.
4. The optical fiber jumper cable bend radius is 3 cm. Smaller radii
can cause excessive optical loss and/or fiber breakage.
5. If multiple transmitters are installed in the chassis allow
sufficient room for adequate ventilation; otherwise the units may
overheat causing possible safety hazard or equipment damage.
6. Fuses: The 7180M chassis does not have fuses. If the unit fails, pull
the power supply out from the chassis and then push it back in.
7. When several units are installed on one 7180M chassis, ensure
that the total units’ current consumption (including any LNB
bias) does not exceed 6A.

The 7870 IFL is a 10 – 200 MHz IF fiber optic link used primarily in
short distance, single channel video applications with high input/
output power levels. The 7870 IFL consists of an optical transmitter
(7870T) which receives signals from satellite modems, video
modulators, or exciters and transmits them to an optical receiver
(7870R) via singlemode fiber.
The 7870T and 7870R modules plug into a 7180M, a 3U chassis and
power supply, which enables expansion of the system to
accommodate up to eight Sat-Light™ modules. Accessories include
the Model 7001P Power Supply, the Model 2040 1:1 Redundant
Switch, the Model 2100 Amplifier, and the Model 7050 Serial Optical
Multiplexer, an asynchronous data transceiver.
The 7870 IFL transmits all satellite modulation schemes - digital or
analog. Any FM modulated RF signal is transmitted accurately. The
RF signal is directly modulated and adds virtually no phase noise to
the original signal. The direct modulation, along with extremely flat
amplitude and group delay, guarantees low bit error rate (BER) and
high signal quality, independent of distance.
LEDs, and back panel monitors, and alarms allow for complete
system status monitoring and for interfacing with monitor and
control (M&C) systems. Gain Control at the Receiver sets the RF
level.

2.1 Setting up the Transmitter
2.1 Setting up the Transmitter
1. Place the 7870T in the 7180M Chassis.
2. Apply AC power to the chassis. The Power Supply and Laser
LEDs should be lit.
3. Using an optical power meter, measure the optical power. Insert
the meter’s cable into the Transmitter’s optical connector. Power
levels should be 0.5 mW minimum (-3 dBm).
Alternatively, use a DVM to measure the voltage at:
•
7180M Rackmount: Pins J13-P17 through J13-P24 for the slot
being measured (See
for details regarding J13 pinouts). [7180M Rackmount]
• Standalone: At pin #6 of the 9 pin connector [Standalone]
The signal level should be -4.5 ± -0.3VDC.
4. On the rear panel, connect the coax cable to the RF Input
Connector. The RF LED should be lit.
5. On the rear panel, connect the fiber optic cable to the Optical
Connector.
Table 4 7870T Transmitter Pinout on page20
Note If either LED is not lit, see Chapter 4 Troubleshooting on page25.
Caution When monitoring the voltage outputs use only a high
resistance DVM.

2.2 Connecting the Fiber Optic Cable
2.2 Connecting the Fiber Optic Cable
Before connecting the cable:
1. The fiber optic cable must be either fusion spliced or connected via
FC/APC connectors.
2. Wipe the connector with a lint-free cotton cloth.
3. Note the polarity key of the optical connector before inserting.
To connect the cable:
1. Line Up the Polarity Key.
2. Insert the connector
3. Tighten the connector
Caution Do not apply any glue, silicon adhesive, or any other
material to the fiber optic connector!

2.3 Setting Up the Receiver
2.3 Setting Up the Receiver
1. Place the 7870R Receiver in any of the 7180M Chassis, unless a
2040 RF Switch is installed. (See
on page 12.)
Note If a 2040 RF Switch(es) is being installed, then slots 2 and/or 5
of the 7180M are reserved for the switch(es).
2. Apply AC power to the chassis. The Power Supply’s LED should
be lit.
3. Using an optical power meter, measure the optical power coming
to the Receiver from the fiber optic cable. The power levels of the
Receiver should be the power level measured at the Transmitter
2
minus the fiber loss
Alternatively, use a DVM to measure the voltage at:
• pins J13-P9 through J13-P16 for the slot being measured (See
Table 5 7870R Receiver Pinout on page21 for details regarding J13
pinouts) (7180M Rackmount). The voltage level should be 1 V
for each 1 mW measured at the Receiver input.
• at pin #5 of the 9 pin connector (standalone)
4. On the rear panel, connect the coax cable to the RF Output
Connector.
5. Adjust the Gain Control Potentiometer to give the desired output
power. Using a small screw driver, turn the potentiometer
(located on the front panel) to increase or decrease the gain.

2. Fiber loss is defined as:
(attenuation/km x length (km) of the fiber optic cable) + (0.5 dB ×
number of connectors).
For example if a signal with an optical wavelength of 1310 nm is
transmitted over a link 10 kilometers long which had two connectors
the loss would be:
(0.4 dB/km × 10 km) + (0.5 dB × 2) = 5.0 dB

2.4 Powering the IFL
• Transmitter power requirement: +14 VDC @ 200 mA
• Receiver power requirement: +14 VDC @ 250 mA.
• The Standalone Transmitter/Receiver is powered by a Foxcom
supplied external DC power supply.
• The Rackmount Transmitters/Receivers are plugged into the
rackmount chassis. The chassis can accept and power up to eight
units.
Note At temperatures below10°C, the Transmitter’s internal heater
will require an additional 100 mA. The Transmitter’s total
power requirement will then be 300 mA.
Caution Ensure that there is a good airflow around the chassis
rackmount.

2.5 Connecting the Back Panel Jumpers
2.5 Connecting the Back Panel Jumpers
On the rear panel of the 7180M Back Panel are product selectors (JP1 to JP4). The 3 pin selectors (male) are the
connecting point between the slots and the back panel. One pin is for the transmitter/receiver (Tx/Rx), one is for the
optional 2040 1:1 Redundant Switch, and one is for the 7180M. A 2 pin jumper (female) is placed on the relevant pins to
complete the connection between the 7180M and the units. For example, if a 2040 Switch is being used, the jumper is
placed on the Switch-7180M pins.
To connect the jumpers:
1. Each jumper has two sets of pins, upper and lower. The upper pins are labeled SW (Switch) and the lower pins Tx/Rx.
2. If the 7180M has Tx or Rx units only, place all jumpers on the lower two pins.
Figure 8 Jumper Installation: Tx and Rx only
3. If the 2040 Switch is installed in Slot 2, place the JP1 and JP2 jumpers on the higher two pins and the JP3 and JP4
jumpers on the lower two pins.

3.4.3 7180M and Redundancy Switching
The 2040 Switch provides optional 1:1 redundancy switching for all
Foxcom Interfacility Links. If the customer chooses to add
redundancy switching to the link, the pin connector jumpers need to
be moved.
Detailed instructions on moving the jumpers are provided in the
Model 2040 1:1 Redundant Switch Installation and User’s Guide
(Document Number 93-005-26-A2).

4 Troubleshooting
The 7870D Interfacility Link unit was tested before it left the factory.
However if you are experiencing difficulties see the list below for
possible solutions. if you are still experiencing problems, attempt to
isolate and identify the malfunctioning unit before consulting
Foxcom’s technical support.
Table 8 Troubleshooting the Transmitter
Problem Possible Cause
1. Laser LED not on a. No DC power to the unit. Possible
power supply problem or AC power
input problem. Check the power
supply fuse.
b. Verify LSRI monitor is between -4.2
and -4.8VDC. If not, laser may have
overheated. Disconnect power or
remove plug and allow to cool. Try
again with better airflow.
c. If an optical power meter is avail-
able, measure the optical power out
of the transmitter. The power
should between 0.5 mW[-3 dBm]. If
an optical power meter is not available, use another receiver to determine if there is optical power
emerging from the transmitter (use
a 5 meter jumper cable). If there is
no optical power, then the transmitter unit is malfunctioning.
If any or all the above are not within
the guidelines, the transmitter unit is
faulty.
2. The RF LED is not
lit
The input signal is less than -28 dBm;
verify RF signal strength [RSSI] is≤0.2
VDC. [See
Pinout
Table 4 7870T Transmitter
on page20]. Even if slightly out
of range, the unit may still function,
although it will register an alarm
condition.
3. RF LED illuminated
- with no input
signal
7870 Interfacility Link Installation and User’s Guide page 25
Foxcom proprietary information
Unit may be receiving stray RF “pick
up”. Solution: provide RF input or use
necessary termination input.`
Table 9 Troubleshooting the Receiver
Problem Possible Cause
1. Lack of RF signal
present at Receiver,
yet optical power is
functioning.
2. No optical power,
LED not
illuminated.
3. Optical power light
illuminated with
disconnected optical
input.
4. The RF LED is not
illuminated.
If a spectrum analyzer or power meter
is not available then use a DVM and
adjust the gain control for RF signal
strength (RSSI) so that the reading is
> 0.2VDC. (See
Pinout
on page21).
Table 5 7870R Receiver
Conclusion: If signal still not present
then transmitter input stage amplifier
or receiver amplifier is defective.
Contact factory.
a. Transmitter is not functioning, see
above.
b. There is a break or severe bend in
the fiber optic cable. Use an optical
power meter or another
functioning receiver unit to verify
optical power coming down the
fiber.
c. The connector is dirty. Clean it.
d. Optical power too low, too many
splits, too long a distance (thus
exceeding optical budget). System
may still function without LED
illuminated although at reduced
performance.
Damaged (leaky) photodiode. Unit
may still function, otherwise contact
Factory for service.
Verify that the RF signal strength
(RSSI) is <0.2° VDC.

The unit has an FC/APC angle polished optical connector for very high optical return loss
performance. The units are specified into single mode fiber i.e. 9/125 micron core diameter.
Full performance is specified only for low return loss optical plant - meaning that the fiber
must be fusion spliced and all connections or splices must have a return loss greater than -60
dB. With these guidelines in mind, link lengths beyond 20 kilometers (DFB based products)
can be achieved with high performance. Specific performance and/or design assistance is
available by request from Foxcom.
If there is low/no signal or noisy signal at a Foxcom module, the connector should be cleaned.
Dirt on the inside connector tip can impair the flow of light causing problems in signal
transmission. Foxcom modules are sealed but dirt can occasionally enter during installation
and alignment.
The input and output optical ports of all Foxcom equipment are known in the fiber optic
world as bulkhead ports. Foxcom uses
FC/APC connectors.
The following materials are representative of the types of cleaning materials that should be
used for cleaning the fiber optic ports and connectors. They are available from several
suppliers.
